Random Number Generation In the first three programs, the user has been asked for input. This program will be different. Rather than asking the user how many values are in a set of numbers or even what the values are, a random number generator will be used to determine the size of a set and the actual values in the set. To use the random number generator, first add a #include statement for the cstdlib library to the top of the program: #include Next, initialize the random number generator. This is done by calling the srand function and passing in an integer value (known as a seed value). This should only be done ONE time and it MUST be done before actually getting a random number. A value of 1 (or any integer literal) will generate the same sequence of "random" numbers every time the program is executed. This can be useful for debugging: srand(1); To get a different series of random numbers each time the program is run, the actual time that the program is run can be passed as the seed value for the random number generator. This is done as follows: srand(time(0)); If the time function is used, make sure to include the ctime library as well. Note: the two srand instructions that are listed above are simple examples of how to use the instruction. In a program, ONLY ONE version will be used. Now that the random number generator has been initialized, a random number can be generated by calling the rand function: num = rand(); The above line of C++ code will generate a "random" integer between 0 and RAND_MAX and saves the value in an integer variable named num. RAND_MAX is a pre-defined constant that is equal to the maximum possible random number. It is implementation dependent but is guaranteed to be at least 32,767. Modulus division can be used to restrict the "random" integer to a smaller range: num = rand() % 7; will produce a value between 0 and 6. To change the range to 1 through 7, simply add 1: num = rand() % 7 + 1; To get random values that are within a specified range that starts at a value other than 0 or 1: num = minimum_value + (rand() % (maximum_value - minimum_value + 1)); So, to get values within the range 3 - 17: num = 3 + (rand() % (17 - 3 + 1));

Basic Program Logic Initialize the random number generator using a seed value of 30. Note: other seed values may be used to produce different results. However, the version that is handed in for grading MUST use a seed value of 30. Generate a random number between 1 and 500. This will be the number of values in the first set. Display the number of values in the set with an appropriate label. In a for loop that executes exactly "number of values in the first set" number of times, generate a random number (no restrictions), and display the random number. Make sure that there are only 5 values displayed per line. Generate a random number between 1 and 300. This will be the number of values in the second set. Display the number of values in the set with an appropriate label. In a while loop that executes exactly "number of values in the second set" number of times, generate a random number (no restrictions), and display the random number. Make sure that there are only 7 values displayed per line. Generate a random number between 1 and 100. This will be the number of values in the third set. Display the number of values in the set with an appropriate label. In a do while loop that executes exactly "number of values in the third set" number of times, generate a random number (no restrictions), and display the random number. Make sure that there are only 8 values displayed per line. Symbolic Constants This program MUST use at least 6 symbolic constants. Three of the constants should be for the maximum values for the sizes of the sets of numbers. The values should be 100, 300, and 500. The other three constants should be for the maximum number of values to be displayed for each set of numbers. The values should be 5, 7, and 8. More symbolic constants may be added to the code if necessary. Output Run 1 (using srand(30);) on Windows PC The for loop will generate 137 random values. 2491 107 3440 23380 31295 3435 10003 14278 10010 1416 29422 9949 5151 30942 11775 27052 21986 25150 32292 2993 4799 13348 6968 30563 5406 12777 4991 14602 21238 26938 12100 25555 3728 24521 14272 19748 29838 18754 9534 4653 23339 22913 30845 7104 1732 1794 17238 5218 6040 20889 9374 1186 1228 24931 15182 2473 18610 4604 21729 23059 8778 15858 23294 3325 4105 24186 17495 22367 26586 21346 3281 13213 12387 26439 30949 10072 8073 25608 10310 7050 25142 19322 15300 31442 4441 2142 4720 2572 30767 11152 25089 12069 4034 2433 11894 6701 21423 19430 25853 1198 21547 19378 7700 31549 10568 18242 19182 25934 11125 18648 21016 16205 5444 20811 24412 15082 29297 6909 27366 14772 31 2316 15269 21993 25188 5837 26868 28044 21256 23414 8058 25529 11658 30234 11598 3126 31844
